Hi, How can I validate records during “creating records”?
For example primary key using “E-MAIL”, when I need to garantee that I will have just one record with an specific e-mail; When I put an email that alread exists in database, I expect to receive this messages below
… This e-mail already exists;
… This product already inserted;
Obs: I’m using Firebase in my APP
Get the data from the database first using get record collection. In this ,
In the first output you display a notice that the data exists
This example did not works. Is there some Youtube Video with this explanation?
I tried to use GET DATA COLLECTION and did’nt works too;
Your app variable called
data Must hold the data from firebase for this to work.
